问题 单项选择题

在软件开发项目实施过程中,由于进度需要,有时要采取快速跟进措施。()属于快速跟进范畴。

A.压缩需求分析工作周期

B.设计图纸全部完成前就开始现场施工准备工作

C.使用最好的工程师,加班加点尽快完成需求分析说明书编制工作

D.同其他项目协调好关系以减少行政管理的摩擦

答案

参考答案:B

解析:进度压缩指在不改变项目范围、进度制约条件、强加日期或其他进度目标的前提下缩短项目的进度时间。进度压缩的技术有以下几种:①赶进度(也称作赶工)。对费用和进度进行权衡,确定如何在尽量少增加费用的前提下最大限度地缩短项目所需时间。赶进度并非总能产生可行的方案,反而常常增加费用。②快速跟进。这种进度压缩技术通常同时进行有先后顺序的阶段或活动,即并行。例如,建筑物在所有建筑设计图纸完成之前就开始基础施工。快速跟进往往造成返工,并通常会增加风险。这种办法可能要求在取得完整、详细的信息之前就开始进行,如工程设计图纸。其结果是以增加费用为代价换取时间,并因缩短项目进度时间而增加风险。根据上述概念,"压缩需求分析工作周期"、"使用最好的工程师,加班加点尽快完成需求分析说明书编制工作"属于在尽量少增加费用的前提下最大限度地缩短项目所需时间的做法,即赶工。"设计图纸全部完成前就开始现场施工准备工作"属于并行展开相关活动,即属于快速跟进。而对于"同其他项目协调好关系以减少行政管理的摩擦"这一选项,间接防止进度的拖延,而非实质性推进工程进度,故不属于赶工,也不属于快速跟进。因此应选择B。

You may know about “ junk food” like French fries. But do you know about “junk sleep”?

Recently, a British survey found that electronic(电子) products in teenagers bedrooms are affecting(影响)their sleep.

The survey was done among 1,000 British kids from 12 to 16. It found that thirty percent of them got just 4 to 7 hours sleep every day. But doctors say they need 8 to 9 hours.

Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.

“This is very worrying.” Said Dr Chris Idzikowski, a British expert, “We call it ‘junk sleep’, It means you don’t get enough sleep and the quality of the sleep is bad, too. If you don’t get good rest, you don’t perform well in school the next day.”

The survey found that 40 percent of the kids felt tired each day, with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, Mp4 or TV IN THEIR BEDROOM. And many of them have all three.
